I would not go with 19s cause tires can get real expensive for 19s trust me cause I got 19s in the back.

As for 20s I had them on my Mustang and it did effect the performance but looks is what I was mostly going for. So if you care anything about performance don't get 20s. I mean if you have a ton of power then it doesn't really matter but you could still tell a difference.

As for the vette I put 20s and 19s on it and they were also forged aluminum but with chrome which adds alot of weight too, and it looked great but right away I could tell a big difference in accelleration and wanted the car for what it was a sports car, a light sports car at that so I went back to stock sizes with wheels weighing around 25lbs. Fly like a butterfly sting like a SOB!!! haha

P.S. Do not put 20s on a car unless it's lowered!!!! PLZ it looks gawdawful!!!

 

Are we forgetting the actual wheels being 2 inches bigger in diameter? Hence, rotating mass. You could put a 20 profile tire on it, won't help any. There is still a 2inch increase in overall size.

 

Definitely depends on the tire and wheel choice. Many plus-size rims will significantly increase weight and rotating mass, but not all of them are so detrimental. Mine for instance are forged (drops ~9 lbs. per corner) w/ Ferrari-grade Pirelli rubber. So, as far as handling and grip is concerned I'm very well covered in most circumstances. The lower sidewall reduces flex, thus improving handling response. Conversely, potholes are a bigger threat, but the shock/spring combo does a darn good job of countering this.

Old school is a great thing as it lead to what many of us enjoy today. On the other hand, since I enjoy playing the devil's advocate, 'old' is just that. The computer/fuel injection replaced carburation due to increased efficiency and more tuning parameters. Modern tire and wheel combos also provide options not formerly available.

Traction - well that's a different story for me at least. I blame it on the twin-screw usually. Sometimes it's just me being overzealous and not easing into the throttle.

For me the choice would be easy, old muscle to intimidate and cruise, new muscle to get me around reliably and in comfort. Oh wait, that wasn't making a choice now was it. Here's hopin' I get to experience both in my lifetime!

IROK, you can further set yourself apart with that v6 by throwing a snail up top. Get the musclecar look with the hi-tech power approach. All the choices are what keeps this hobby interesting. Good luck to ya!

 

I think these would look awesome!!!

i get it man it's cool. i just thought his post was funny.

 

i don't understand this post!!

 

Ferrari Grade Rubber? OK?

 

lol on his Bullitts in his SIG

 

noone here has anything to say about 19's. why wouldnt this be a middle road for both looks and performance. someone posted about tires being expensive thats all.

 

I haven't found any difference in accelleration at all. I have wider tires in the back with my 20" chrome set-up, so handling is the same or better. One thing that is absolutely worse is ride quality. Obviously with less rubber, less bumps are absorbed so you feel the road more. But to me, it's worth it.

P.S - I also have my stock 17's to switch out for the winter in a few weeks, so I'd keep your stockers if you do decide to switch.

Edit: Here is my car stock and below it is my car now...just in case you wanna see another black 'stang before and after.
